During the development and testing of the application programs that will run on your System/34, it will be necessary to create and then modify many display formats. The screen design aid utility program (SDA) has been

developed to help you do this. Instead of laying out your displays on grids and then coding Sand D specifications for $SFGR or Work Station Utility (WSU), you can build your displays directly on the display screen. When the screen displays are as you want ttiem, SDA will create the $SFGR or WSU source member for you. SDA also gives you the ability to add new formats to a member, modify existing formats, and delete formats you no longer need.

SDA also gives you the option of creating or modifying menus on the display screen. To create a new menu, a skeleton menu is displayed, and you fill in the blanks. When you add new operator procedures to an application, SDA lets you add them to the existing application menu.

SDA can also be used to generate a WSU program. Use SDA to build a format source member that contains your displays. Then use SDA to generate a basic WSU program that corresponds to the source member. You can then use SEU or SDA option 6 to add any calculations you require. Because SDA does not create the disk file descriptions (F- and I-specifications), you must create the source descriptions of the disk files being used before you compile the WSU program.

Another SDA option simplifies the creation of the RPG source specifications needed for a WORKSTN file. Use SDA to build a source member containing your displays. Then use SDA to build a skeleton RPG II program that corresponds to that source member. You can then use SEU to complete your program, or you can use the include function of SEU to place the generated RPG II source statements in your existing source program.

Introduction

Introduction vii

SDA supports both the 1920- and the 960-character display. In many cases, figures and examples are shown using both displays, but when there are minor differences between the two displays, figures and examples are shown using the 1920-character display only.

SDA enables customers to define display screen formats using ideographic characters. All functions of SDA will support Ideographic Characters.

Generally, a good practice to follow when you are using SDA is to record the format member names, format names, and menu names before you begin to create, add to, or update those format members or menus. The LlSTLlBR command is useful for determining the names of existing format members or menus; refer to the System Support Reference Manual for more information.

Notes:

1. This manual describes how to use the SDA program; it does not describe the procedures, control commands, and/or utility programs -you can use instead of the SDA program. For information on those topics, refer to the System Support Reference Manual.

2. The SDA procedure cannot be nested within a procedure.

3. The SDA procedure reserves bytes 1 through 104 of the local data area for its use. Therefore, any user data in these bytes will be destroyed.

4. If the SDA procedure resides in a user library other than the system library (#LlBRARY), you will only be able to create, add, or update format members that are in the specified user library. If the SDA procedure resides in the system library (#LlBRARY), you will be able to create, add, or update formats that are in any user library on the system.

This diagram shows the general logic flow of the SDA program.

SOA SIGN-ON

Enter one or more of the following parameters on the Command display:

(1 ) (2) (3) (4) (5) (6)

SOA [source] ,[inlib] , [sfgrload] , [sfgrprint] ,[outlib] , [sfgrlib]

The parameters you enter depend on the SOA program function requested.

Only parameter 3 (sfgrload) is required, if needed by the function, because all other parameters have defaults. Enter commas as needed to maintain proper placement of parameters.

Note: The SOA sign-on procedure is the same in ideographic mode or nonideographic mode. The screen prompts are ideographic if the work station is in ideographic mode. The work station operator must answer with

alphanumeric responses. If you want to create ideographic screen formats, you must be in the ideographic mode. Ideographic mode is entered by specifying yes to the ideographic prompt at sign-on. If you want to update ideographic screen formats, then you must be in the ideographic mode.

Parameter (1) source

(2) inlib

(3) sfgrload

(4) sfgrprint

(5) outlib

(6) sfgrlib

Description

The name of the source member to be processed. If you are processing formats, the default is SCRNSPEC. If you are building a menu (SDA menu option 7), the maximum length of the name is 6 characters and the default is SCRNSP.

The name of the library in which SDA will find the member to be processed or displayed. The default is the system library (#LlBRARY). If you enter a name in this parameter, it will be the default for parameter 5 (outlib) and parameter 6 (sfgrlib).

The name you want assigned to the load member created by $SFGR. If you do not enter a name, $SFGR will not be run when you finish running SDA, and the load member formats will not be generated.

Controls printing by $SFGR on the system list device.

(SDA printing is controlled by command function key 6.).

Enter YES, NO, or PARTIAL. The default is YES.

YES causes the printing of Sand D specifications, buffer descriptions, all messages, and lists the indicators used.

NO causes the printing of only termination messages, together with the statement causing the error.

PARTIAL causes the printing of input and output library names, screen format member names, and all messages together with their related statements.

The name of the library in which SDA should write the created or updated source member or the menu command text and display text source members. The default is the system library (#LlBRARY) or the library name you entered in parameter 2 (inlib).

The name of the library in which $SFGR should write the object format member. The default is the system library (#LlBRARY) or the library name you entered in parameter 2 (inlib).

The display will change to the SDA menu when you enter the SDA command.

Introduction xi

Notes:

1. Entering SDAH presents an explanation of the utility.

2. If you did not enter a source member name, or if you enter HELP SDA, SDA displays the Screen Design Aid screen, which shows the required parameters.

You can use this display to enter or change any SDA sign-on parameter.

Defaults are displayed, but you can enter your own parameters in place of the defaults. (See Appendix C.)

3. If you still did not enter a source member name (parameter 1), the following message will appear on the display screen:

SDA-0001 ENTER NAME OF MEMBER TO CREATE OR PROCESS If you want to accept the default (SCRNSPEC for formats, SCRNSP for menus), press the Enter / Rec Adv key. Otherwise, enter the source name to be processed if parameter 1 is needed by the SDA function being selected.

If the system is in ideographic mode, you must use nonideographic

characters to name source members and formats. Source member names or format names can be up to eight characters long and must begin with the characters A through Z, or

#,

@, or$. The remaining characters can be any combination of alphanumeric characters. Source, menu, or format member names cannot contain commas (,), single quotes ('), blanks, question marks (?), slashes (/), or hypens (-). Source, menu, or format members cannot have the names ALL, DIR, NEW, or SYSTEM, and should not have a name that has $ or

#

in the first position of the name.

4. Screen messages and prompts issued by SDA are ideographic if the work station is in ideographic mode. Operator responses to the SDA ideographic messages must be alphanumeric.

Introduction xiii

Enter the number associated with the program option you want to perform.

The chapters in this book correspond to the option selection numbers.

The first display also asks three questions and indicates the default answers.

COL IND MODE? ENTER Y OR N. DEFAULT IS Y.

Enter Y to enable the Column-indicator (COL IND) mode of SDA. This mode is used for the create, add, and update options. Column indicators and the active screen name are displayed on line 1, and line 1 is not available for entry when "

this mode is enabled. Enter N to work with all 24 (1920-character display) or 12 (960-character display) lines of the display. Command function key 8 can be used to show whether the Blank or Attribute screen is active when the Column-indicator mode is disabled.

WSU FORMAT MEMBER? ENTER Y OR N. DEFAULT IS N.

Enter Y to cause SDA to generate the S- and D-specifications used by WSU.

Enter N to cause SDA to generate the S- and D-specifications used by

$SFGR.

Note: Because SDA places data in columns 15 through 18, 23, 24, and 26 in the generated D-specifications, warning messages WSU-0111 and WSU-0262 are issued when these D-specifications are compiled in a WSU program. Data is placed in these columns for the update option of SDA.

AUTOMATIC PROMPTING? ENTER Y OR N. DEFAULT IS N.

Enter Y to enable automatic override prompting. This is used for the create, add, and update options. SDA will display the field attributes for each input and output field that will contain execution time data. You can change any item on the display. Enter N to disable automatic prompting.

Select your menu option and ensure that the questions are answered correctly;

then press the Enter / Rec Adv key. The first display of the option you select will appear on the display screen. (If you entered anything other than a number from 1 through 8, the SDA menu is redisplayed.)

Help displays are available at any time while you are using SDA. In addition, command function keys can be used to modify certain SDA functions and alter the sequence of others. These topics are discussed in the following sections of this chapter.

SDA attempts' to diagnose some errors when data is entered. When a syntax error occurs, the data in error is redisplayed in reverse image. When there is a relational error between two or more fields, those fields blink. When there are fields with required entries that are left blank, the entire prompt and any data you entered is redisplayed. Correct the error by retyping the corrected response or by deleting the response and taking the default.

Options 1, 2, 3, and 5 provide a source statement resequence option. This allows you to select whether or not to have the first five columns of your

HELP DISPLAYS

SDA provides you with two levels of help:

• A help menu that allows you to select displays that define many of the basic functions of the SDA program. (The SDAH command is described below.)

• Help displays that provide basic information about the current SDA session and basic descriptions of the SDA create and update functions (the Help key function).

There are two ways to display the help menu using the SDAH command:

1. At sign-on, enter SDAH on the Command display.

2. At any other time during SDA program operation:

a. Press the Attn key.

b. Take the 1 option.

c. Enter: SDAH

d. Select the needed help option from the help menu.

e. End SDAH with command function key 7.

f. Resume the interrupted task with command function key 1.

The help menu appears as follows:

SDA COMMAND FUNCTION KEYS AND TEMPLATE

SDA supports the command function key operations shown on the SDA portion of the IBM System/34 Keyboard Template, GX21-7660. These command function keys let you modify certain SDA functions and alter the sequence of others.

The template and command function keys appear as follows for nonideographic and ideographic keyboards, respectively.

The SDA command function keys have the following meaning:

Command Function

Key Definition

Return to the S-specification display and begin the cycle again. This key performs the Enter/ Rec Adv function only when pressed during SDA option 3.

2 Display the Blank screen. This key performs the Enter / Rec Adv function only when pressed during SDA option 3.

3 Not used by SDA.

4 Not used by SDA.

5 Allows use of lowercase letters. These letters are valid on the Blank screen and on a blank menu display. Lowercase letters can be printed by the IBM 5256 Printer and by the IBM 5211 Printer with a

96-character belt. (See note 2 below.) This key performs the Enter /Rec Adv function only when pressed during SDA option 3. In update mode (option 3), the Attribute screen allows use of lowercase letters without the use of this key.

6 Reverse the print status. If SDA information is being printed, command function key 6 will suppress printing, and vice versa. Printing is on the system list device. The current print status can be determined from the first help display (that is, when the Help key is pressed during the S, Blank, or Attribute screens of SDA options 1, 2, or 3). The initial condition does not print.

7 End of job. If you press command function key 7 after you have selected a menu option, the option is terminated (the update or menu build options allow you to either terminate or continue). If you press command function key 7 while the SDA menu is displayed, SDA is terminated.

8 For the create, add, or update options, command function key 8 tells you whether you are using the Blank or Attribute screen. The halt message tells you which display is active; take the O-option to return to the current operation.

9 Use to exit from the S-specification, Blank screen, Attribute screen, and menu build displays.

10 Use when displaying formats to blank the screen before the next format is displayed.

Notes:

1. Command function keys 1, 2, and 6 are valid only on S, Blank, and Attribute displays.

2. Command function key 5 is valid only on Blank, Attribute, and menu displays. (On the Attribute display, command function key 5 displays the Blank screen and allows lowercase letters to be used.)

3. A command function key is processed as an Enter / Rec Adv key on the system Input-Output display.

Introduction xix

SDA SIGN-OFF

Use command function key 7 to end SDA:

• While a menu option is active, command function key 7 terminates the option.

• When the SDA menu is displayed, command function key 7 terminates SDA and returns you to the Command display.

SDA DISPLAYED MESSAGES

SDA messages are described in the Displayed Messages Guide.

SDA requires special handling for two halts: FILE FULL and LIBRARY FULL.

Recovery must be done at the display station where the failure occurred.

File Full Halt

SDA supports a source member of up to 5000 source statements. Take the 2-option to the halt and follow the recovery procedure described in

AppendixA.

Library Full Halt

Take the 3-option to the halt, condense the library, and follow the recovery procedure described in Appendix A.

Chapter 1. Create a New $SFGR/WSU Source Member

After you select the option to create a new $SFGR/Work Station Utility (WSU) source member, the following occurs:

1. SDA prompts for general display information (the S-specification fields), and you enter them.

2. You enter the layout of the display on a blank display screen.

3. You enter the attribute codes for each field on the attribute screen.

4. SDA prints an image of the display (optional).

5. You enter additional field attributes and overriding data (optional).

6. SDA writes all specifications for this format to a work file, optionally prints the specifications, and repeats the cycle of 1 through 6 until you terminate the option.

7. You indicate whether or not you want the source resequenced, and SDA writes the work file back to the source member.

Chapter 8 and Appendix B show how you can use SDA to create a WSU program.

Figure 1-1 shows the logic flow of the create and add functions of SDA, and the following text describes steps 1 through 7 in detail.

The entries on this display· are defined as follows:

D

^Format Name: The name of the format being defined. The format name can be any combination of alphanumeric characters and must be no longer than eight characters. The first character must be alphabetic (A-Z), #,$, or

@.

The format name cannot contain commas (,), single quotes (,), or imbedded blanks. The format name should not contain $$

in the first two positions of the name. Avoid naming formats ALL or LIST. SDA DISPLAY (option 4) and DELETE (option 3) use LIST and ALL as keywords. Duplicate format names cannot be used in the same load member, and should not be used in the same source member.

II

WSU Format ID: Work station utility format identifier.

II

Start Line Number: The line on the display where this format is to begin.

Valid entries are V for variable, or a line number no greater than the number of lines on the display screen. If V is specified, a number can be entered in a prompt of the Display Call Up Utility display. The default is line 1. Leading zeros are not required, but the number must be

right-justified. If you use this field, layout the display relative to line 1 of the blank screen as if line 1 were the start line number.

II

^Number of Lines to Clear: The number of lines, beginning with the start line, that are to be set to blanks before this format is displayed. The default is 24. Leading zeros are not required, but the number must be right- justified.

II

Lowercase A/lowed: Lowercase letters are valid. Enter Y for yes, N for no; the default is N.

II

Return Input: Return all input fields to the user program even if no data keys are pressed. Enter Y for yes, N for no; the default is Y.

Blink Cursor: Whether to blink the cursor for this display. Enter Y for yes, N for no, an indicator number (xx) for an indicator; the default is N.

IE

Erase Input Fields: The erase input fields entry allows the program to erase the input fields and output/input fields on a display and to reset the keyboard by setting an indicator and redisplaying the format. The format is not transmitted to the display station. You might want to request erase input fields when an application requires an operator to enter information into the same display time after time. ~

If an indicator (01 through 99) is specified, an erase input fields operation can be performed for this format. Input fields are erased and the

keyboard is reset if the specified indicator is on when the format is displayed; all other fields are unchanged. A normal put operation is performed if the indicator is off when the format is displayed.

If Y (yes) is specified, an erase input fields operation occurs every time this format is displayed. Ordinarily, Y should not be specified since all entries on the following field definition specifications are ignored when the format is displayed. Instead, if an erase input fields operation may be performed for this format, an indicator should be specified.

If N (no) is specified or the entry is left blank, an erase input fields operation is not allowed for this format.

Note: If the entry causes an erase input fields operation to occur and there are no input fi~lds currently defined on the screen, a display station error occurs.

III

Override Fields: An override operation allows you to replace data in output fields when the same format is redisplayed.

Entry Y

N or blank

Description

An override operation is performed every time the format is displayed.

An override operation is not performed.

A normal output operation will occur.

An override operation is performed when the indicator is on.

1. All field attributes not controlled by an indicator are unchanged.

2. The protect field attribute in the attribute screen that is controlled by an indicator is ignored during an override operation.

3. An override operation on a format not currently displayed causes unpredictable results because only a portion of the format is sent to the work station when the· override operation is done.

Suppress Input: Whether to suppress input (yes) or return input (no) to the user program. Enter Y for yes, N for no, an indicator number (xx) for an indicator; the default is N. (WSU does not support this field.)

IE

Key Mask: A string of numbers and / or alphabetic characters that identify keys to be enabled or disabled when this format is displayed. The field is up to 16 characters long and cannot contain embedded blanks. The numbers and alphabetic characters can be in any order.

The remaining entries are for control within WSU programs. See the WSU Reference Manual for details on these fields.

After you make the needed entries to the S-specification display, press command function key 9. If there are errors, the fields in error will blink, and you can reenter the data.

BLANK SCREEN'

The Blank screen allows you to layout your display format. When the display is in Full-screen mode, this display is completely blank; when the display' is in Column-indicator mode, line 1 shows the column numbers and the display title. Figure 1 -3 shows an example of a Blank screen when the display is in Column-indicator mode; the screen layout is complete.

The Blank screen can have a mixture of both ideographic fields and nonideogprahic fields.

Figure 1-3. Completed Display Layout on a Blank Screen in Column-Indicator Mode When the Blank screen appears, use the entire display screen (except for the line with column numbers across the top when the display is in

Column-indicator mode) as a work area to layout the display. SDA needs one blank position before each field on the display for attributes. In addition, nothing can be entered in columns 1 or 2, line 1. So the first field cannot start before column 3 of line 1.

Line 1 on the Blank screen corresponds to the starting line number on the S-specification. For example, if you specified a starting number of 12, the first line of this screen appears on line 12 of the actual display. Therefore, the number of lines for the display is limited to the number of remaining lines, (in this example, 13 lines remain; 'that is, lines 12-24).

If, when laying out the display, you want to duplicate lines, enter single quotes (') in both columns 1 and 2 below the line to be duplicated. SDA will duplicate that line for you. However, if you are coding WSU, do not use a si~gle quote in a constant (prompt). SDA recognizes a single quote as a single character;

internal quotes in WSU P-constants will terminate that field prematurely if you do an SDA format update.

Create Source Member 1-9

When you complete the display, press command function key 9. This causes the image just entered to be redisplayed for attribute placement.

Note: Anything entered into line 1 when the Column-indicator mode is active will be ignored.

Ideographic fields that start on one line and continue onto the next line of the display can cause problems if a character is split by the end of the line. When building ideographic fields that will extend onto more than one line, you should start the field so that the ideographic shift-out character is in an

even-numbered column on the screen.

When laying out Message Identification Code (MIC) fields, place the MIC number (4 digits) followed by the message member identifier (2 digits) in the first six positions of the field. The rest of the field is left blank and should be large enough to contain the message. The field type should be M on the Attribute screen, with no data type attribute, and a T or t should be used to indicate the end of the field. The following chart indicates which message member identifiers are associated with the message members containing the messages.

Identifier U1 or blank U2

P1 P2 M1 M2

Message Member Containing the Message User-1 message member

User-2 message member Program-1 message member Program-2 message member

SSP level-1 message member (##MSG1) SSP level-2 message member (##MSG2)

Note: For additional information on MIC fields, see Constant Data in the

$SFGR section of the System Support Reference Manual.

ATTRIBUTE SCREEN

The attribute screen allows you to define the attributes of the fields for your display format. Two characters are used to define field attributes. Character 1 indicates the field type, such as input field, execution-time output field, or input/ output field. This first character is placed in the space before each field on the screen. If you omit the field type attribute, the field is defined as a normal-intensity output constant field.

If the field you are defining has input capabilities,' you must define a second attribute for the data type. Character 2 indicates what type of data is to be keyed into the field. Except for ideographic fields, this character is placed immediately after the field type attribute and overlays the first character of the field on the attribute screen. If you omit the data type attribute, and the first character of the field is not N or S, the field's data type is defined as alphanumeric.

If you want additional field attributes, such as underline, reverse image, or color, place an * as the field type attribute. SDA,.wifl prompt you via the override screen

The following charts show valid attribute characters and how SDA interprets them.

The following rules apply to field attributes specified for SDA:

1. All fields must be separated by at least one blank.

2. Attributes require a maximum of two positions (the first position preceding the field and the first position of the field). The second attribute character is valid for fields defined by K k, 8 b, or I i attributes in character ·1. The override field attribute screen is used to define the second attribute for fields that are defined in the ideographic mode. The screen displays additional .attributes for the following conditions:

a. The work station is in ideographic mode.

b. First attribute characters of K, 8, and I are used for a field.

c. The ideographic shift-out character is the first character of the field, and / or a second attribute character that is invalid or that is not recognized by SDA is keyed.

For example, on the display in Figure 1 -3 you have a field that will contain a phone number:

876-5643

This field is an input alphanumeric field. Therefore, starting in the blank immediately preceding the field, you enter ia. (If the field begins in column 1, enter the first attribute in column 80 of the preceding line.) The field on the display will now appear:

ia76-5643

Do not be concerned that the 8 has been overlaid by the attribute. This will not affect the finished format.

3. The second character is ignored when you specify C c, E e, or M m for character 1.

Note: A field containing a mixture of alphanumeric and ideographic characters is supported by SDA. If the ideographic data in the field is composed of extended ideographic characters, you should be aware of the following considerations:

• If the field starts with an alphanumeric character, the extended ideographic characters are shown as an invalid ideographic symbol when the object format is displayed by either SDA option 4 or a user program.

• You should define the field containing a mixture of alphanumeric' and extended ideographic characters as two separate fields: one field containing the alphanumeric data and one field containing the ideographic data. An ideographic shift out character should be the first character of the ideographic field.

4. Fields missing a first attribute or having an attribute not recognized by SDA will default to output constant of normal intensity.

5. There are three ways to indicate where a field ends; you can do the following:

a. Enter a T (uppercase or lowercase) in the blank position immediately following the last character of the field. The example from step 2 would then appear as follows:

ia76-5643t

b. Enter the field attribute for the next field if only one blank separates the fields. In this case, a T is not needed. For example, you have

CHECK NUMBER 1234

on the display and these are two separate fields.

CHECK NUMBER is an alphameric constant and will default to c.

1234 is an input only field with field characteristics in (normal intensity, numeric input). The display screen would show

CHECK NUMBERin234t

after the attributes and a terminating t following the second field have been entered.

c. Let SDA insert an implied T if the field is meant to include all remaining display screen positions through column 80 of the last line on the display.

Note: $SFGR errors may occur if a start line number other than 1 was entered on the S-specification.

Only lines that were duplicated on the Blank screen should use the duplicate attributes feature on the Attribute screen.

ADDITIONAL FIELD ATTRIBUTES AND OVERRIDING DATA The SDA Field Attributes display appears:

• If automatic prompting of field attributes was requested on the SDA menu, the first input orexecutiE>n time data field (I, E, B, or K attribute) that you defined on the Blank screen is displayed in reverse image (with any attributes that you entered on the Attribute screen), and you can change attributes for every field.

You are prompted to change other I, E, B, or K fields in the format in the order in which the fields appear on the screen (left to right, top to bottom). You will be prompted for any field with an asterisk (*) in the first attribute position.

• If asterisks were entered on the Attribute screen and automatic prompting was not selected, the first field with an asterisk in the attribute position is displayed in reverse image. You can then change that field. You are prompted to change any other asterisked fields; the changes are made in the order in which the fields appear on the screen. You will not be prompted for any other fields in this format.

On the Blank screen during an ideographic session, a field with the first attribute characters of K, B, or I, and the second attribute either missing or undefined, is displayed in reverse image on the screen. SDA asks for additional attributes for the field.

Prompting does not occur if data type attributes of N, A, or S are used with field type attributes of K, B, or

I.

Create Source Member 1-15

After you change field attributes and press the Enter key, the S-specification display appears.

Note: If you are entering additional field attributes but do not want syntax check- ing performed on a specific field, enter Y for the following prompt:

ENTER Y TO BYPASS SYNTAX CHECKING.

Lines 5 through 8 of the 1920-character display and lines 2 through 5 of the 960- character display contain up to 256 bytes of data from the display image

associated with the field being overridden (that is, the field is being defined further than input allowed, output data, or constant type). This field is shown in reverse image to distinguish it from other fields. In Figure 1-6, NAME is the field for which the overriding data is being entered. This data cannot be changed. On the remain- ing lines, you can enter overriding data.

The field name generated by SDA can be overridden on this display. You may want to do this if you are generating formats for WSU or are planning to create an RPG skeleton program.

Valid input values are displayed in parentheses on the 1920-character display only.

An xx value indicates an indicator number. The rightmost valid option is the

$SFGR default. A blank for self-check indicates a non-self-check field. A blank for adjust/fill indicates blank fill for signed numeric; no fill for all other types of fields.

A blank for edit code indicates no editing.

If you used an asterisk as an attribute for this field, be ,sure to differentiate between an output constant (c) and program execution time output (blank) by filling in the constant type.

Press the Enter/Rec Adv key when all overriding data associated with the field has been entered. If the attributes blink, an error has occurred. Reenter the correct attri butes.

Figure 1-6 shows an example of the override Field Attributes display.
